COILS - Round Tube Coils-Enhanced tubing, advanced sinusoidal fin design for optimal performance. Extensive use of 5/16” and 3/8” diameter tubing keeps refrigerant charge to a minimum.

Optional, ElectroFin E-Coat provides a uniform, flexible coating over the entire coil with immeasurable impact on thermal conductivity. 100% coverage is assured by the application process, even in the hard to reach center portions of the coil, without bridging between the fins. We recommend the application anytime a remote condenser is located near a salt water coast or a potential source of corrosive airborne particles.

FANS - Swept fan blades are designed as part of the motor, not an addition to it. Precise matching of these two components increases energy efficiency and reduces sound pressure to lower levels.

MOTORS - Direct drive external rotor motors offer uncompro-mised energy efficiency, low sound, and the longest trouble free life available. The RC8 & RCU series have fully enclosed motor lead raceways to protect wiring.

CABINETS - G90 galvanized steel cabinet provides years of durable finish protection and aesthetics. The RC8 & RCU series have tall venturi fan panels to add to our uncompromised energy efficiency and ultra-low sound. Fully baffled fan cells prevent “wind milling” and enhance performance.

R EMOTE CONDENSERS

E ASY INSTALLATION

Remote Condensers

After uncrating, the condenser easily lifts into place with the use of eye bolts located on top of the unit. At ground level, the condenser can rest on a solid surface such as a concrete slab.

On roofs, the unit should be placed on channels or an I-beam frame.

DESERT AIRE has a condenser for every application. Our com-plete line of direct-drive condensers compliments the wide range of our dehumidification offerings.

Head pressure controls automatically maintain condensing pressure at ambient temperatures as low as -20°F.

M ULTIPLE REFRIGERATION CIRCUITS

DESERT AIRE’s large commercial condensers are available in single or dual-circuit designs to match the needs of the dehumidifier. Each condenser fan is independently controlled to limit refrigeration migration and maintain design condensing temperatures.

Elevation above sea level has an effect on the performance of air-cooled condensers. The unit capacities shown in the Performance Table must be multiplied by the correction factors in Table 1 to correct for various elevations.

DESERT AIRE’s Remote Condensers are designed with a commitment to excellence that will provide you with years of reliable service.

All DESERT AIRE equipment is consistently manufactured to high performance standards for efficient, reliable service.

Our Remote Condensers are easy to install too.

NOTES: All data contained in this document is subject to change without notice. Please consult factory for most current data.

Condensers in this brochure are limited to an elevation difference of 10 feet (RC below) and a maximum linear distance of 50 feet. Consult factory for high-lift model options.

RC STANDARD SERIES

Desert Aire’s RC series of condensers are for customers seeking the most economical solution for their capacity requirements.

This series of condensers offer quality sound and power benefits.

Enhanced motor technology using an 1100 RPM blower/fan combination affords lower noise levels and significant energy savings.

RCU QUIET SERIES

The RCU series offers exceptional sound, energy and capacity solutions. Featuring 500 RPM motors coupled with specially designed blades that are precisely mounted in a venturi to pro-vide unprecedented low sound levels. While RCU condensers may require more fans, these units actually require significantly lower power consumption through their optimized blower effi-ciency. (See Figures 2 and 3 for comparisons.)

STANDARD FEATURES

Standard equipment includes a door interlock and a main terminal block for motor lead termination. The RC8 & RCU series includes a main disconnect switch. Standard control panels are rated at 10 kA SCCR when power is supplied with class J fuses.
